Exposer frame size ?

Posted on Thu, 12 May 2005 at 10:33



Hello pioneers,

1. For exposing a frame size of 76x65 inches (graphics four color process), 4 kw Metal Halide is ok ?
2. What is the ideal Exposer frame (inside Beading area) size to expose 76x65 ?
3. What excess space needed outside frame area, so as the blanket to contact with glass ?

Advice please.
Thanks for the time.

1. yes the 4k light will work fine. Higher power = faster burn.
2. size to fit frame - this is a bit tricky in that there are different blanket materials with different degrees of flex. On my frame, I can't go more than about 4-5" to the beading /edge and get the blanket to suck over the inside and outside.

However....in some cases, there is no need to have blanket rubber to the outside if the bead is making a seal - in this case you can go closer, as long as the rubber can make it up and over the frame - it will suck down inside.

if you try and get it too close, you also need to consider the entry point of your vacuum - on my frame it has a metal spreader attached to the vacuum draw string, I don't think I would want this getting jammed into my mesh on a regular basis.

Say a series of holes ? And connect the hose to the blanket frame ?

I do not see any problem.
